Vllo'll'f'lfi Application filed November To o'ZZ w/Lom tmag/ coi'mem:

Be it known thatl, FnANci'szni l MunizEJnwsnI, a citizen of Poland, residing at Adams, in the county of lerlrshire and State of Massachusetts, have in'vented certain new and useful mproven'ients in l'lotor Sleighs, of which the followingl .is a specification.

rllhis invention relates to certain new and useful improvenients in motor sleighs and has for its primary object to provide a motor sleigh having body construction similar to an ordinary automobileand capable of having` the sleigh runners removed and automobile wheels substituted therefor and mounted upon the usual afles to adopt the device for use either as an automobile or motor sleigh.

^ Another object of the invention is to provide a motor sleigh capable ofbeing constructed in a full size working apparatus with such novel features embodied therein that will be present in the toy sleigh.

A still further object of the invention is to provide a motor sleigh wherein the rear' runners have motor driven propelling serews associated therewith while the runners are carried by a frame supported on the rear aXle -housin` of the sleigh structure in a manner to p-ermit pivotal or rocking movement of the frame and runners inoident to the use thereof.

lVith the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangenient of parts hereinafter more fully described, shown in the accompanying` drawings and claimed.

In the drawings, wherein like reference characters designate corresponding` parts throughout the same, V

Figure 1 is a side elevational view of the combined automobile and motor sleigh constructed in accordance with the present invention, the automobile wheels and sleigh runners being illustrated in full lines with the runners or Wheels capable of being removed whenever desired.

Figure 2 is a top plan view of the rear runners with the propelling' screws and operating' means therefor and furiher showing` the front runners with the steering` devices,

Figure 3 is a fragmentary front elevational view of the front runners,

Figure 4 is a cross-sectional view thru the rear runners showing the propelling screws SLEIGE.

and the pivotally 'inounted frame' 'for the c runners,

H'ig'ure 5 is al eross-sectional view of the rear runners showing the Operating devices the propelling screws. lig'ure 6 is a detail sectional view showing resilient niounting for the reir endvof the ive shaft and the guide devices t-herefor, Figure 7 is a detail seetional view, showing the forward end of one of'the i'ear runners in top plan with the propelling` serew keyed to the driven shaft ournaled in the runner.

Referring; inore in detail to the accompanying crawings, and particularly to F iv. 1 there is illu trated a combined motor sleigh and automobile wherein the 'body 1 is in the form of ordinary automobilebody having rearax'les 2 and 3 respectively iich the usual automobile wheels 4; are mounted. i

ll-.Then the. device is eniployed as a motor sleigh, the drive shaft 5 extending rearwardiy from .the transmission housing'is diseonnected at its rear end from the usual differential and has an elongated pinion 7 fixed thereto as clearly shown in Fig. 6`l the end of the shaft 5 being positioned between the side arms of the vertical guidesS that depend from the body 1 of the structure, the rear end of the shaft being' normally influenced in an upward direct-ion by the eoil spring 9 attached at its upper end as at 10 to the body 1 while the lower end thereof is attached as at 11 to 'the rear end of the shaft 5.

A frame structure is pivotally supported beneath the rear end of the body l, preferably between the rear axle housing and the vehicle body, a pair of spaced brackets 12 secured to the under side of the body as illustrated in Fig. -lz having a horizontal shaft 13 journaled therein and supporting at their outer ends, the bearing ends 14k forwardly and rearwardly directed arms 15 that are connected at their outer ends by cross brace bars 16. The brane bars 16 extend laterally of the arms 15 as at 16a and are do'xvnwardly directed as at 17 as shown in 1 and then forwardly and upwardly direeted to providevrunners 18.

The lower ends of the downwardly oirected 1oortions 17 of the side frames at each side of the vehicle body has a horiYontal shaft 19 journaled therein as shown in 7 ad upon which shaft the hub portion 20 of a screw propeller 21 Ais keyed as at 22. The driving devices for the screw propellers' 21 include pinions 23 lreyed to the shaft 19 with a sprocket e'fiain 24; passing over the pinions 7 and 23 as shown in detail in Fig. 5, the lower section of the sprocket chain being guided by the rollers 25 carried by the adjacent brace bar 16. It will therefore be seen that when the drive shaft 5 is rotated, met-ion thereof is communicated to the screw propellers 21 thru the medium of the sprooket Chain and pinions above described to effect the propulsion of the motor sleigh as will be readily .understood from an inspection of Fig'. 1.

It will be noted that in view of the pivotal mounting of the arms 15 upon the rod 13, the rear runners and driving devices associated therewith are permitted limited. pivotal movement beneath the body l of the sleigh to compensate for unevenness in travel. The sprocket chain 24; is maintained in a taut condition by the spring Suspension 9 for the rear end 'of the drive shaft 5 irrespective of the position of the rear runners relative to the body of the sleigh.

The front steering` runners are supported at the front end of the vehicle Chassis by the lmounting plate 26, a Vertical bolt 27 as shown in Figs. 2 and 3 pivotally supporting the central meeting ends of the cross arms28 that carry runners 29 at their outer vpresent invention, it is nevertheless to Abe understood that minor changes may be made therein without departing from the spirit and scope of the lnvention as claimed.

That is claimed as new is n a motor sleigh, an axle;v a frame consisting of a pair of arches pivoted at their central portions to the sleigh adjacent and above theJ axle, a pair of transverse meinbers carried by the lower ends ofthe arch members and having` their endsiextending downwardly in parallelism and provided With oppositely disposed runner portions at i their lower extremities; shafts journaled between the downwardly extending parallel portionsof the transverse members and provided with `propeller serews, and means to drive said shafts simultaneously.

In testimony whereof I afi'ix niy signature.
